Assessing of Saltwater Intrusion in Ghiz-Nekor Aquifer (North Morocco) Using Electrical Resistivity Tomography

The implementation of suitable monitoring and protection actions is fundamental for protect freshwater resources in costal aquifers. Electrical resistivity tomography (ERT), has proved, in many case, to be very effective for illustrating with higher resolution near-surface resistivity anomalies for a wide range of environmental problems, including saltwater intrusion. According ERT models obtained in this survey, the saltwater intrusion in Ghis-Nekor aquifer can be explained both by the presence of deep faults that cross the impermeable layers of silts and clays, or by a lateral facies change in the shallow deposits favoring saltwater intrusion into the aquifer
